<h2 class="title">4. Manejando eRRoRes</h2>

<p>Reeborg sigue las instrucciones al pie de la letra - lo cual es
bueno, pero también malo. Por ejemplo, escribe el siguiente
programa (fíjate en las mayúsculas):</p>

<pre>
Move()
turn_off()
</pre>

<p>Intenta ejecutar el programa. Reeborg protestará. Esto es
así porque para Reebor las letras M y m son distintas.</p>

<h3 class="try">Your turn</h3>

<p>Make sure you try it to see exactly what happens. In the future, if you
see the same kind of complaint from Reeborg, it might help you discover
what's wrong with your program. In other words, you will find how to
recognize one kind of <i>bug.</i> You will learn more about <i>bugs</i> a bit
later. Well, you might learn sooner rather than later, if you write your own
programs with bugs in them!</p>

<h3 class="quiz">Quiz</h3>

<p>What is the shortest valid program you can write? By valid program, we
mean one that Reeborg will execute without giving any error messages. Make
sure you try it to see if this simple program works as expected.</p>
